British police stopped and handcuffed two prominent Bahraini human rights activists following protests in London on Wednesday against the visit of King Hamad bin Isa al-Khalifa, the ruler of Bahrain.

The police handcuffed Alwadaei and took him to a police car for “disturbing the peace”, he told the Middle East Eye.

He was then released and told to leave the area.

Alwadaei said “police should be investigating the torture allegations coming from Bahrain, the abuses committed by the regime, rather than targeting activists or journalists covering the King’s visit to the UK.”

A victim of torture in Bahrain, Alwadaei was arrested after taking part in the February 2011 pro-democracy protests. He later moved to the UK.

Ali Mushaima, the second activist who was arrested by police, is son of Hassan Mushaima, a political activist who has been sentence to life in prison by Bahraini regime.

He is considered a prisoner of conscience by Amnesty International.

Prior to the Bahraini king’s visit, BIRD published a letter signed by Alwadaei in which he called on the British Prime Minister Theresa May to raise the issue of human rights in Bahrain, where there is an ongoing crackdown against activists.

"The United Kingdom’s influence is strong in Bahrain, but it has not been used to benefit human rights substantively. The only way to positively impact the human rights situation there is to make use of your leverage and to criticize these issues in public,” read the letter.
